This report provides an analysis of ocean acidification data collected from Brewers Bay and Hind Bank. This data was originally being used to try to detect if upwelling at deeper sites (i.e. Hind Bank) led to periodic acidification conditions.
| Sites | Location | Reef Complex | Depth (m) | Latitude | Longitude | Description |
|---|---|---|---|---|---|---|
| Brewers Bay | St. Thomas | Nearshore | 6 | 18.34403 | -64.98435 | High cover Orbicella annularis reef near UVI |

EcoPAR first deployment 1/25/22-3/28/22
EcoPAR second deployment 10/14/22-3/7/23
SBE-37 second deployment only 10/15/22- 3/7/23. First deployment did not work from sensor/user error.
SeaFet first deployment: 12/7/21-3/28/22 (Brewers) 12/13/21-3/27/22 (Hindbank)
SeaFet second deployment: 10/15/22-3/7/23 (Brewers) 10/15/22-10/29/22 (Hindbank). There were sensor issues with data after 10/29/22, All values were negative. Sea-Bird suggested that the instrument slowly become flooded with water. Could not recover missing/damaged data.
SAMI deployment: 10/15/22-3/7/23 (Brewers) 10/15/22-2/28/23 (Hindbank). We only have the second deployment. During the first deployment, the sensor had issues and needed to be sent back for repairs. Sunburst thinks air got in the pump and caused it to get locked up. They recommended not to use the data. Could not recover missing/damaged data.
Finalized Temperature over time for all instruments during the 2nd deployment time frame.
